What this trial studies

This exploratory multicenter study involves up to 300 subjects diagnosed with obstructive sleep apnea who are being evaluated for airway surgery. Participants will undergo standard evaluations for airway surgery, along with a simple, non-invasive measurement of the pharyngeal width inside their mouths, which takes about 2-3 minutes. The goal is to determine if this measurement can predict the absence of complete concentric collapse at the soft palate, potentially improving surgical outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with obstructive sleep apnea who are being evaluated for Inspire Upper Airway Stimulation surgery.

Not a fit: Patients who are unable to lie supine for the measurement or deemed unfit by the investigator may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of surgical evaluations for patients with obstructive sleep apnea.

How similar studies have performed: While this approach is exploratory, similar studies have shown promise in improving diagnostic accuracy for obstructive sleep apnea treatments.
